Build and initialise environment and download dataset

sudo singularity build main.sif Singularity
singularity run main.sif -p initialise

Feature extraction (Increase NUM_JOBS if running on HPC for speed up)

singularity exec main.sif python sastvd/scripts/prepare.py
singularity exec main.sif python sastvd/scripts/getgraphs.py

Train model (Training takes around 1-2 hours using GTX 3060)

singularity exec --nv main.sif python sastvd/scripts/train_best.py
